UV absorber
Pansi pa kuwala kwa dzuwa ndi fluorescence, mapulasitiki ndi zinthu zina za polima zimakumana ndi makutidwe ndi okosijeni wokhazikika pansi pa cheza cha ultraviolet, chomwe chimayambitsa kuwonongeka kwa ma polima ndi kuwonongeka kwa mawonekedwe ndi makina.Pambuyo pakuwonjezedwa kwa ultraviolet absorber, kuwala kwamphamvu kwa ultraviolet kumatha kutengeka mosankha ndikusandulika kukhala mphamvu yopanda vuto kuti itulutsidwe kapena kudyedwa.Chifukwa cha mitundu yosiyanasiyana ya ma polima, mafunde a ultraviolet omwe amawawononga nawonso ndi osiyana.Zotengera zosiyanasiyana za ultraviolet zimatha kuyamwa cheza cha ultraviolet ndi mafunde osiyanasiyana.Mukamagwiritsa ntchito, ma ultraviolet absorbers ayenera kusankhidwa malinga ndi mitundu ya ma polima.
UV absorbers akhoza kugawidwa m'magulu otsatirawa malinga ndi kapangidwe kawo mankhwala: salicylates, benzones, benzotriazoles, m'malo acrylonitrile, triazine ndi ena.
